Crochet sock size chart
Crochet sock sizes are based on foot circumference and foot length. A women's medium foot measures about 8.5 inches around and 9.75 inches long, and a men's medium foot about 9.5 inches around and 10.5 inches long. Crochet socks about 10 percent smaller than the foot circumference for a snug fit.

How do you measure a foot for crochet socks?
Measure a foot for crochet socks by recording the circumference around the ball of the foot and the length from heel to longest toe.
- Wrap a tape measure around the widest part of the foot, across the ball, while standing.
- Measure from the back of the heel to the tip of the longest toe.
- Multiply the circumference by 0.9 to get the target sock circumference.
What yarn is best for crochet socks?
The best yarn for crochet socks is a super fine sock yarn with about 75 percent superwash wool and 25 percent nylon, which balances warmth, stretch and durability.
Why do crochet socks need negative ease?
Crochet socks need negative ease because crochet fabric stretches with wear, and a sock that matches the foot exactly will slip and bunch inside a shoe.
Source and method: Foot measurements are typical approximations for each shoe size range; feet vary widely, so measure the wearer. Sock circumference is computed as foot circumference × 0.9.
Frequently asked questions
What hook size is used for crochet socks?
Crochet socks are usually made with a 2.25–3.5 mm hook and super fine sock yarn.
How much negative ease do socks need?
About 10 percent negative ease at the foot circumference gives a snug crochet sock.
Should I trust shoe size alone?
No. Shoe size only approximates foot measurements, so measure the wearer when possible.
